Sentry Go Integration，如何指定错误级别？

According to the official docs https://docs.sentry.io/clients/go/ you can log errors in Sentry from a golang project with:

// For Errors
raven.CapturePanic(func() {
    // do all of the scary things here
}, nil)

// For panic
if err != nil {
   raven.CaptureErrorAndWait(err, nil)
   log.Panic(err)
}

This works like a charm, the problem is in Sentry both functions are logged with level 'Error'. Anyone knows how can the logging level be specified for each call? In Python is very explicit, but I don't see it for Go.

I followed the advice in the comments, and came up with this:

// sentryErrorCapture sends error data to Sentry asynchronously. Use for non-Fatal errors.
var sentryErrorCapture = func(err error, severity raven.Severity, tags map[string]string, interfaces ...raven.Interface) string {
    packet := newSentryPackage(err, severity, tags, interfaces...)
    eventID, _ := raven.Capture(packet, tags)
    return eventID
}


func newSentryPackage(err error, severity raven.Severity, tags map[string]string, interfaces ...raven.Interface) (packet *raven.Packet) {
    interfaces = append(interfaces,
        raven.NewException(err, raven.GetOrNewStacktrace(err, 1, 3, raven.IncludePaths())))

    packet = &raven.Packet{
        Message:    err.Error(),
        Level:      severity,
        Interfaces: interfaces,
        Extra:      getSentryExtraInfo(),
    }
    return
}

When I want to log an error specifying the level I call: sentryErrorCapture(err, raven.ERROR, nil).
